PROJECTED WINDOW.

Application filed July 14, 1927, Serial No. 205,703, and in JapanDecember 30, 1926.

My invention relates to improvements in windows of the type comprisingaswinging sash provided with horizontal axes pivotally and slidablymounted on rails and a sliding sash provided with counter balances.

The object of the invention is to provide a novel operating mechanismfor windows of this type whereby said swinging and sliding sash may beoperated independently of each other or co-operatively keeping thesliding sash at a desired position.

According to the present invention a chain or rope mounted on a pulleyis connected at one end to the swinging sash and is connected at theother end to the sliding sash by detachable coupling means. A hand ropeattached at the lower side of the swinging sash is passed over a guidepulley arranged 0 on the upper end of the sliding sash and a of theswinging sash. The sashes are closed by pulling the lower one of thehand ropes and opened independently or jointly according to whether thefirst mentioned chain or rope is in engagement or disengagement with thecoupling means to the sliding door by pulling of said second hand rope.

The invention is more particularly illustrated with reference to theaccompanying drawing in which Fig. 1 is an elevation of the improvedwindow as closed and seen from inside.

Fig. 14 is a plan view showing the operation of the modified couplingmechanism.

Referring more particularly to the drawing the window frame (1) isprovided at the upper part of its sides with vertical rails and theupper sash on its adjacent sides and spindles or axes (4) (4) providedatone end with shoe guides that are slidably mounted on said rails (2)(2) as shown in Figs. 8 and 4. The otherend of said aXes are pivoted tothe sides of the swingng sash (3) so that the latter can be proectedoutwardly as shown in Figs. 6 to 9. The sash (3). is provided at itssides with pivoted supporting links (5) (5), the lower end of said linksbeing also pivoted'to the frame (1) so that when the sash (3) is closedsaid links (5) (5) are slightly'inclined outwardly as is shown in Figs.2 and 3.

A grooved pulley (7) is arranged in a recess. (6) formed at the centralpart of the top of the window frame (1), and a chain or One end of saidrope (8) is connected to the upper end of the swing sash (3) and theother end is connected to a coupling piece (10) provided with a groovedpulley (11) on a bracket, the purposes of which will be moreparticularly pointed out hereinafter. A

sliding sash (9) is provided with the usual counter balances (12). Theupper side of the sliding sash (9) is grooved and provided with a seat(13) and a screw bolt (14) between which the aforesaid coupling piece(10) can be clamped so that the swinging sash (3) and sliding sash (9)may be coupled to each other through the chain or rope (8) or may beuncoupled by unscrewing the bolt (14).

The swinging sash (3) is further provided with hand ropes (15) and (16),the upper one (15) hangs freely insidethe sash and the lower one (16)after passing over the guide pulley (11) on the coupling piece (10) alsohangs inside the sash. The free ends of said ropes (15) and (16) can beconnected to each other as is shown in Fig. 1.

A transverse frame member (17) extends across the window frame (1)between the swing sash (3) and the sliding sash (9), and a guide rod 18)is vertically fixed between said transverse frame member (17) and thetop of the frame (1). The coupling piece (10) provided with a guide tube(19) slidably fitted on said guide rod (18) so that the coupling piecemay run smoothly on the rod (18) when the sashes (3) and (9) are openedor closed. Said guide tube is preferably provided with a set screw (notshown in the drawing) whereby the tube may be clamped on the guide rod(18) at the time of the closure so that the sashes may be locked.

In case of necessity, the window may be divided into three parts; theupper part of which being provided with the swinging sash the lower partwith the slidin sash (9) and the central part with a fixed sash in sucha manner that the upper sash is situated by turn outside of the lowersash when the window is closed. frame member (17) is removed and theguide rod (18) is fixed on the fixed sash.

The operation of the improved window is as follows -When the couplingpiece (10) is connected to the sliding sash (9) as shown in Figs.- 2

and 3, and the sliding sash (9) is moved upward the swinging sash movesdownward on the rails (2) by its own weight and the lower side of theswinging sash is pushed outward by the arms (5) (5) so that the sash (3)is projected and the lower side of the sliding sash is opened to formair passages at the upper and lower parts of the window as shown in Fig.6.

Further movement of the sliding sash (9) does not affect any movement ofthe swinging sash, and the sliding sash can be raised to any desiredheight as is shown in Fig. 7. When the lower rope (16) is pulled by handwhen the sashes are in the position shown inFig. 6 or Fig. 7, thecoupling piece (10) is pressed downward by the guide pulley (11) whichcauses the sliding sash (9) to be closed and at the same time theswinging sash (3) is pulled upwardly at its lower end and is as a wholemoved upwardly and is closed as shown in Figs. 2 and 3. The guide tube(9) may be then clamped on the guide rod (18) and the sashes may belocked in their closed position.

When the coupling piece (10) is uncoupled the rope (8) slackens and theswinging sash is projected by its own weight or by aid of the upper handrope (15) pulled downward as shown in Fig. 8. Thus the swinging sash (3)may be opened. while the sliding sash (9) is kept closed. The swingingsash may be closed by pulling the lower rope (16'). The sliding sash (9)may be opened or closed independently of the swinging sash (3) when thecoupling piece (10) is uncoupled as shown in Fig. 9.

The coupling means may be modified as shown in Figs. 10 to 14. A pair ofendless chains or ropes (20) (20) are passed on In this case thetransverse grooved pulleys (21) (22) arranged at both sides of thewindow frame (1). The pivotal axes (4) (4) of the swinging sash arefastened to one side of said ropes (20) and on the other side (20) ofsaid ropes are adjustable collars (23) (23). The sliding sash (9) isprovided at its upper side with a tri-. angular cam (24) projecting itsaxis (25) inside the sash and provided with a finger piece (26) at itsend. ranged at one side of said cam to prevent the free rotation of thelatter. The cam (24) is provided with rods (28) (28) slidably passingthrough guides (29) (29). The other ends of the sliding rods (28) (28)are forked at (30) (30)v and said forked ends project at the other sidesof the endless rope (20) (20). i

shown in Fig. 13, the forked ends (30) (30) are disengaged from theendless ropes (20) (20) and the swinging sash may be opened irrespectiveof the sliding sash (9) by pulling the upperhand rope (15)-so that saidsash is projected "outward. to form an air passage at the upper part ofthe window as shown in Fig. 11. The sliding sash (9) ing sash (3) to adesired position to form an air passage at the lower part of the wmdow.

The sashes are closed by pulling the lowerv hand rope (16) whereby theswinging sash (3) is pulled upward and at the same time the sliding sash(9) is pressed downward so that they may be closed as shown in Fig. 12.

When the cam (24) is rotated to the position shown in Fig. 14, theforked ends (30) (30) of the sliding rods (28) (28) are brought inengagement with the endless ropes (20) (20) at the collars (23) (23) sothat the sliding sash (9) becomes coupled to the swinging sash (3) andthey may be. opened or closed co-operatively as stated be- A spring (27is ar- When the cam (24) is kept in the position may also be openedirrespective of the swingconnecting one end of said chain or rope tosaid swinging sash, means for detachably connecting the other end tosaid sliding sash, said other end carrying a pulley, hand ropes securedto the top and bottom of said swinging sash the lower one of whichpasses over the guide pulley arrangedon said chain or rope,substantially as described.

2. In the improved projected window, a swinging sash and a sliding sash,pulleys arranged at the upper and lower ends of the window frame at bothsides and a. pair of endless chains or ropes vertically passed thereonone for each pair of pulleys, each endless chain or rope connected toapivotal axis of the swinging sash, adjustable collars secured to saidendless chains or ropes, forked sliding rods secured on said slidingsash, cain means to operate said sliding rods to stantially asdescribed.

In testimony whereof I have aflixed my signature.
